Title: Data transmission system
Inventor: DENNERLEIN LUDWIG DIPL ING
IPC: H04L12/40
Filed: 1987-11-14
Abstract: In a data transmission system, the data bus of which is connected via a pull-up resistor to an operating voltage source, the parasitic parallel capacitance of the data bus, together with the pull-up resistor, form an RC section which prevents potential steps on the data bus. In practice, this limits the length of the data bus to a particular length. The circuit arrangement presented is intended for increasing the length of the data bus. For this purpose, a current source circuit is connected to the data bus. The field of application is, for example, the extension of a data bus of an I-squared-C-bus.

Title: Electromechanically operated pressure modulator for antilock and traction control systems
Inventor: KARNOPP DEAN PROF
IPC: B60T8/42
Filed: 1988-02-03
Abstract: A pressure modulator for antilock systems situated between a multi-circuit master cylinder and at least one wheel brake cylinder has hitherto been designed with a control piston which can be moved only in the pressure reducing direction by an electric motor by way of an internal screw thread and a spindle. The said arrangement is not suitable for combined antilock and traction control operation, whereas the new pressure modulator takes account of such operation. In a pressure modulator (100), designed with a first chamber (4) and a second chamber (13), a connection is made between the first chamber (4) and a multi-circuit master cylinder (1) and between the second chamber (13) and at least one wheel brake cylinder (2). With the admission of a hydraulic pressure to a first piston shoulder (12) facing the first chamber (4) and by means of a spindle (30), engaging in the internal screw thread (72) and moved by an electric motor (20), a movement of the control piston (8) in the direction of the second chamber (13) connected to the wheel brake cylinder (2) is produced and hence a build-up of pressure in a normal braking sequence and in a braking sequence necessary for traction control. <IMAGE>

Title: Safety device for uncocking the firing hammer of a self-loading pistol
Inventor: LUDWIG WALTER
IPC: F41A17/74
Filed: 1988-11-09
Abstract: The safety device consists of a sear which is mounted in the firing hammer of the self-loading pistol such that it can pivot and can be moved with the aid of an operating element from an active position, in which an impact surface of the sear is opposite the firing bolt end, into a safe position in which the sear cannot reach the firing bolt end. If it is intended to uncock the firing hammer from the cocked position without any danger, then the person shooting uses the thumb of the firing hand or of the free hand to press against the operating element and to allow the firing hammer, which is released by simultaneous operation of the trigger, to move slowly forwards into the uncocked position. As a result of the fact that the sear cannot reach the firing bolt when the operating element is depressed, inadvertent firing of a shot is prevented.

Title: Process for the production of an X-ray mask
Inventor: HORI MASARU
IPC: G03F1/00
Filed: 1988-12-16
Abstract: The invention relates to a process for the production of an X-ray mask which enables microstructuring of an X-ray absorber of heavy metal without a multilayer resist film with the aid of a merely single-layer resist film and with the use of the resist film as a qualitatively high-performance protective film on the pattern of the X-ray absorber. The process described is carried out, in particular, by forming an X-ray absorber (13) on an X-ray transparent thin film (12) and forming a photosensitive organic resist film (14) on this absorber, and by exposing and developing the resist film to form a resist mask for the formation of an X-ray absorber pattern (13), exposing the resist mask (14) by means of synchrotron radiation (15), and selectively etching the X-ray absorber (13) using the cured resist mask (14) to form the X-ray absorber pattern (13). <IMAGE>

Title: Dung conveyor
Inventor: HAIGES ADOLF
IPC: A01K1/01
Filed: 1989-03-06
Abstract: Dung conveyors of the prior art have a push rod which can be pushed to and fro by a linear drive means, such as a piston rod, and on which a number of dung sliders are articulated and can be swivelled between a transverse advanced position and a return position parallel to the rod. In this case the frontmost slider in particular, designed as pressure flap, is left to itself and open to the forces which are inadvertently exerted on the sliders when these are moved to and fro by means of the push rod in a straight excrement channel leading from the byre (stall) into the open. A disadvantage of the above is that a correct transition of the slides between the advanced position and the return position is not guaranteed when the direction of movement of the push rod changes. The object of the invention is therefore to ensure that at least the frontmost slider (pressure flap) at all times moves satisfactorily between its two positions (advanced position and return position) and is not blocked in intermediate positions which lead to operational failures. The solution according to the invention is that at least the frontmost slider (3) can be moved into its advanced position and its return position by force upon the advance or return stroke of the piston rod (8) or a corresponding drive element. An advantage of this solution is that the pressure flap in particular, on which everything basically depends, [lacuna] its function in each direction of movement of the ...
